I have a strange problem that I hope you can help me with. I'm not sure which club would be the appropriate forum, but here goes anyway. I just completed my HT room and my 803S's and HTM3S sounds fantastic. Unfortunately, I had to use CCM 65 ceiling spekers in the back because of my lack of space and room layout. That's where my problem eminates from. My furnace/ air conditioning unit is at the back of the seating area. This was the only design possible because of the shape of the room. I put bi-fold doors in front of the furnace, but when the air conditioning fan comes on, since it is so close to the seating area, the noise is very noticable. I'm sure that when winter sets in the furnace sounds will be even louder. Other than installing solid doors and door frames, which is what I am planning to do if I can't find some other way to reduce the noise, does anybody know of any materials that I can put behind the bi-fold doors to reduce or eliminate the sound. Remember, I will need to get to the furnace periodically to service the unit and the front of the furnace is bout 6 to 8 inches from the door. (I have made sure that the furnace is able to get plenty of air from a source on another wall.)

Our dedicated (:B sorry Lex) HT room's entry is a 94" high x 63" wide opening on it's left side. I've managed to balance the soundstage in spite of this big hole, but have been wanting to put something there to stop noise coming in and movie sountracks and music going out.

Today I put on that 1st disc from 1967 called The Doors and truly enjoyed it so hence I thought of this Thread::: What is your favorite Doors Tune? Mine... -
Noise
In the context of loudspeaker measurements made during the design process, noise refers to any unwanted electrical or acoustic signals that can interfere with the accuracy of the measurement. Noise can be introduced through various sources, and it can affect the reliability and precision of the measurements, making it essential to minimize its impact for accurate loudspeaker evaluation. Sources of noise include:- Background Acoustic Noise: During loudspeaker measurements, ambient

Signal-to-Noise Ratio (SNR)
The signal-to-noise ratio (SNR) is an important parameter that helps evaluate the performance and quality of the audio output. In the context of audio, SNR refers specifically to the ratio of the desired audio signal (the sound produced by the loudspeaker driver) to the background noise generated by the speaker itself or the overall system.
The formula to calculate SNR in decibels is:...
SNR (dB) = 10⋅log10(PowerSignal/PowerNoise)25 July 2023, 15:20 Tuesday
